Description

technical field

[0001] The invention relates to the technical field of coatings, in particular to a neutron radiation-resistant waterborne polyurethane coating and a preparation method thereof. Background technique

[0002] With the development of nuclear power industry, many nuclear reactors need to be built. There are corresponding protective layers, shielding layers, and reflective layers inside the current nuclear reactor, which can prevent neutrons from leaking out when the atomic nucleus is working normally. However, if an abnormal accident occurs in a nuclear reactor, a large amount of neutrons will leak out, especially when a lethal neutron flow occurs under certain circumstances, these leaked neutrons will bring great harm to humans and the environment . Neutron radiation is more destructive and dangerous than gamma rays in nuclear radiation, so the protection against neutron radiation is more important.

[0003] At present, heavy metals and transition metal oxid...
